• Large size adult NIBP cuff of the 8-Inch Portable Patient Monitor with Touchscreen.
• Limb perimeter: 33-47cm, Cuff width: 17cm.
• The width of the cuff should be either 40% of the limb circumference (50% for
  neonates) or 2/3 of the upper arm length. The inflatable part of the cuff should be long enough to encircle 50-80% of the limb. The wrong size of cuff can cause erroneous readings. If the cuff size is in question, then use a larger cuff.
